John, I still think this is a class loading problem. You didn't say what kind of server you're using. If, for some reasons, that server unpacks all application JARs into a commons local directory and loads the classes from there, it could possibily be so that Barcode4J's META-INF/services/org.apache.fop.fo.ElementMapping file overwrote the FOP one. That way, FOP doesn't find its own fo:* classes and that UnknownXMLObj might be explained. You could try to temporarily remove the Barcode4J FOP extension from the classpath and check if that changes anything.
At any rate, you have to make sure the individual JARs are not merged without special handling for the META-INF/services files and that all of the JARs are associated with the same classloader(-hierarchy).
